Brembo PS13 13mm Non-Radial Master Cylinder
This is a great entry-level master cylinder usually used with the dual-fitting handbrake kits. If you're looking to use a Dominator Pro shorty clutch cap, this is the only master cylinder that will work with the clutch cap.
The optional clutch cap mounts directly on top of the Brembo master cylinder brake reservoir, allowing you to run both a handbrake and clutch with only one handlebar perch instead of two. This saves handlebar space, which is usually very limited on stock clip-ons.
